The UH400a is a digital hybrid synthesized UHF plug-on transmitter compatible with all receivers in the 400, 200 and 100 Series product groups. The DSP-base design allows the transmitter to operate in its native Digital Hybrid Wireless™ mode, or in several alternate modes that are compatible with analog receivers. A unique multi-voltage phantom power feature allows the transmitter to be used with any microphone, including high current condenser types, expanding its usefulness in high-end applications such as motion picture production.
